We extend our theoretical understanding of the effect of key employee mobility on organizational performance. We find that when an organization with an advantageous set of routines loses a key employee to a competitor, the advantaged organization's competitive position is reduced vis‐à‐vis the hiring competitor. What is more interesting is that we also show that the diffusion of an advantageous set of routines through the mobility of key employees may affect competitive advantage in at least two additional ways. Our findings result from an analysis of 412 competitive events between the San Francisco 49ers and all other teams in the National Football League during the 24‐year period when the San Francisco 49ers perfected the routines of a strategic innovation that has become known as the West Coast Offense. First, we find that there is a loss of advantage for the organization when competitors increasingly compete against additional organizations that hired key employees from it. Second, we find that there is a loss of advantage for the organization when competitors expect future competition against additional organizations that hired key employees from it. Our results challenge the traditional argument that socially complex routines create sustainable competitive advantages because they are not easily imitated and do not rely on any single individual. Instead, we show that routines are stable to the loss of key employees, but the advantages derived from them are not. Copyright © 2009 John Wiley & Sons, Ltd.

This research proposes and tests that regulatory foci of small business chief executive officers (promotion focus and prevention focus) relate to firm performance differentially when levels of environmental uncertainty vary. Results suggest that a promotion focus is positively related to firm performance, whereas a prevention focus is negatively related to firm performance. Further, these relationships are moderated by the degree of environmental dynamism such that in more dynamic environments, the relationship between promotion focus and firm performance is strengthened, whereas the relationship between prevention focus and firm performance is negatively affected. The reverse was found for less dynamic environments. Theoretical and practical implications as well as future research avenues are offered.

We integrate the seemingly contradictory theoretical predictions of behavioral and economic perspectives about the relationship between pay disparity and firm performance and show that tournament and social comparison theories are more supplementary than contradictory in nature. Our results show that high levels of firm performance will be found around either meaningfully low or meaningfully high levels of pay disparity. Additional findings indicate that this curvilinear relationship is weakened in the presence of both an heir apparent and high CEO power, and strengthened when top management team members are more eligible as CEOs. These findings suggest that factors that increase or inhibit social comparison or tournament perceptions among TMT members play a role in the strength of the curvilinear relationship between pay disparity and firm performance.
